Can somebody help me understand the various parameters of and their effect upon the power generated by an altenator. I would like to experiment with them, but have some idea of how various designs will produce electicity before I start building stuff.

 

I am guessing the strength of the magnets, their distance to the coil and the length of the coils will affect the power of the current and that the number of coils/magnets, the distance between each coil/magenet and the rpm of the system will affect frequency and voltage of the current but iam unsure.

 

what about the numer of turns in the coils and diameter of the coil wire and the core material of the coils?

 

I was also wondering about the air between the stator and magnets, would different gasses produce better / worst inductance? i wouldn't imagine it would but you never know.

Number of turns in the coil will affect the amount of electricity generated. Basically the more surface area of wire you can surround the magnet by and the faster you can move the magnet, the more current will be induced. Not sure about the core material.

thanks, what equations can be used to calculate the current produced?
